Pairs of specialized guard cells on the leaf surface of higher plants form stomatal pores that control water release and carbon dioxide entry. The patterning of stomata is precisely controlled during leaf development to ensure the correct cellular spacing within the epidermis. The EPIDERMAL PATTERNING FACTOR (EPF) family of small secreted cysteine-rich peptides is important in this cell-to-cell signaling process as the EPF-like peptides can act as either positive or negative regulators of stomatal development. The properties of the EPF-like peptides and how they may interact with putative receptor components, such as TOO MANY MOUTHS (TMM) and ERECTA family proteins, and compete to activate or inactivate the downstream kinase cascade are discussed.
